Only two burger chains received A grades for their antibiotic policies, in a collaborative report published last year on antibiotic use in meat supply chains. That honor went to Shake Shack and BurgerFi, while Wendy's received a D-, and pretty much all remaining fast food fiefdoms received F grades (McDonald's, Burger King, Sonic, Jack In The Box, Culver's, Hardee's, In-N-out, Fuddrucker's, Five Guys, Whataburger, Steak n Shake, etc.). While everyone may have their fave burger joint, it's clear that Shake Shack and BurgerFi are leading the better burger movement with all-natural, hormone- and antibiotic-free meats.
